BeanNameAutoProxyCreator拦截器拦截某个实现类方法的步骤

第一步：配置实现MethodInterceptor的切面

public class OutsideInvokeLogInterceptor implements MethodInterceptor{
	private static Logger log = Logger.getLogger("outsideInvoke");
  
	@Override
	public Object invoke(MethodInvocation invocation) throws Throwable {
        String methodName = invocation.getMethod().toString();
        Object returnValue = invocation.proceed();
        if (returnValue == null) {
            log.warn("调用 " + methodName + "is fail,返回的result结果为空,方法入参为:(" + parseArguments(invocation.getArguments()) + ")");
            return ResultDTO.getFailureResult(BSErrorCode.INTERNAL_ERROR, BaseKeyMsgCode.RETURN_RESULTDTO_IS_NULL);
        }else{
            if(returnValue instanceof ResultDTO){
                ResultDTO<Object> resultDTO = (ResultDTO<Object>)returnValue;
                if(!resultDTO.isSuccess()){
                    log.warn("调用 " + methodName + " is fail ,方法入参为:(" + parseArguments(invocation.getArguments()) + ")"
                         + "返回值：" +resultDTO.getCode() + "," + resultDTO.getKey());
                } else{
                    log.info("调用 " + methodName + " is success ,方法入参为:(" + parseArguments(invocation.getArguments()) + ")");
                }
            }
        }
        return returnValue;

	}
}

 

<bean id="outsideInvokeLogAdvice" class="com.ali.luna.commons.service.interceptor.OutsideInvokeLogInterceptor" />

第二步：配置切点

<bean id="methodPointcut" class="org.springframework.aop.support.NameMatchMethodPointcut">
        <property name="mappedNames">
            <list>
                <value>add*</value>
            </list>
        </property>
    </bean>

第三步：配置自动代理

    <bean id="outsideInvokeLogInterceptor" class="org.springframework.aop.support.DefaultPointcutAdvisor">
        <property name="pointcut" ref="methodPointcut"/>
        <property name="advice" ref="outsideInvokeLogAdvice"/>
    </bean>
    <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
        <property name="beanNames">
            <list><value>activityService</value></list>
        </property>
        <property name="interceptorNames">
            <list>
                <value>outsideInvokeLogInterceptor</value>
            </list>
        </property>
    </bean>
